(Submitter supplied) We describe the anti-leukemic activity and mechanism of action of T-3775440, a novel irreversible LSD1 inhibitor. Cell growth analysis of leukemia cell lines revealed that acute erythroleukemia (AEL) and acute megakaryoblastic leukemia cells (AMKL) are highly sensitive to this compound. T-3775440 treatment enforced transdifferentiation-like phenotypic change from erythroid/megakaryocytic lineages into granulomonocytic lineage. more...

(Submitter supplied) T-3775440 is an irreversible inhibitor of the chromatin demethylase LSD1. Here we describe the anti-cancer effects and mechanism of action of T-3775440 in small cell lung cancer (SCLC). T-3775440 inhibited proliferation of SCLC cells in vitro and retarded SCLC tumor growth in vivo. Our results argue that LSD1 plays an important role in neuroendocrine-associated transcription and cell proliferation of SCLC via interactions with the SNAG domain proteins INSM1 and GFI1B. more...

(Submitter supplied) Lsd1KO and ATRA treatment in Hoxa9/Meis1- and MN1-transformed myeloid progenitor cells LSD1 has emerged as a promising epigenetic target in the treatment of acute myeloid leukemia (AML). Inhibition of LSD1 has been shown to induce differentiation and facilitate the responsiveness of AML cells to all-trans retinoic acid. We used two murine AML models based on retroviral overexpression of Hoxa9/Meis1 (H9M) or MN1 to study the effect of Lsd1 knockout in AML. more...

(Submitter supplied) The histone demethylase LSD1 is deregulated in several tumors, including leukemias, providing the rationale for the clinical use of LSD1 inhibitors . In acute promyelocytic leukemia (APL), pharmacological doses of retinoic acid (RA) induce differentiation of APL cells through degradation of the PML-RAR oncogene. APL cells are resistant to LSD1 inhibition or knock-out, but LSD1 inhibition sensitizes them to physiological doses of RA without altering the stability of PML-RAR, and extends survival of leukemic mice upon RA treatment. more...

(Submitter supplied) Mutations in transcription factor Growth Factor Independence 1B (GFI1B) cause inherited bleedings with varying intensity possibly caused by different effects on the transcriptional function of GFI1B. We studied transcriptomic changes of normal and GFI1BT174N,H181Y,R184P,Q287* mutants in megakaryoblast MEG01 cells using RNA-sequencing. Compared to normal GFI1B each variant affected different gene modules with limited overlap between variants. more...

(Submitter supplied) INCB059872 is a selective irreversible inhibitor of Lysine-Specific Demethylase 1 (LSD1) that is in phase 1 clinical trials in hematopoietic malignancies. We evaluated a pre-treatment bone marrow sample of a patient who showed a clinical response to INCB059872 + azacitidine treatment. Single-cell RNA-sequencing (scRNA-seq) showed that INCB059872 caused a shift in gene expression that was associated with GFI1/GFI1B regulation.

(Submitter supplied) INCB059872 is a selective irreversible inhibitor of Lysine-Specific Demethylase 1 (LSD1) that is in phase 1 clinical trials in hematopoietic malignancies. Mice treated with INCB059872 had reduced platelet counts within 4 days of treatment. Here, we used single-cell RNA-seq to study the effects of INCB059872 on hematopoietic progenitor populations within wild-type murine bone marrow. Our results showed that INCB059872 triggered accumulation of megakaryocyte early progenitor cells with gene expression hallmarks of stem cells, which may begin to explain the thrombocytopenia observed in patients treated with LSD1 inhibitors.

Here we sorted cells from this population (Lin- Cd41+ Cd200r3-) and performed RNA-seq to measure gene expression changes caused by INCB059872. more...

(Submitter supplied) INCB059872 is a selective irreversible inhibitor of Lysine-Specific Demethylase 1 (LSD1) that is in phase 1 clinical trials in hematopoietic malignancies. We performed ChIP-seq for histone modifications to define the earliest regulatory events associated with INCB059872 treatment. Changes in acetylation were more dramatic than changes in methylation, and these changes could be traced back to a loss of CoREST activity at GFI1-regulated targets.

We used precision nuclear run-on sequencing (PRO-seq) to define early transcriptional changes associated with INCB059872 treatment. Changes in nascent transcription could be traced back to a loss of CoREST activity resulting in activation of GFI1-regulated targets.

(Submitter supplied) Lysine Specific Demethylase 1 (LSD1 or KDM1A) is one of a number of epigenetic regulators which have recently emerged as candidate therapeutic targets in acute myeloid leukaemia (AML). Pharmacological inhibitors of LSD1 such as the tranylcypromine derivatives have already commenced evaluation in early phase clinical trials; however like all acute leukaemia therapies, it is unlikely that these inhibitors are effective as single agents. more...
